The HTC One isn't even out yet in the US and it already hardly needs an introduction. This is HTC's flagship phone for 2013 and it runs Android 4.1.2 Jelly Bean with the very modern and sleek HTC Sense UI on top. The smartphone has a 4.7" full HD Super LCD3 display that's simply one of the best on the market and it's currently the fastest phone with wonderfully high benchmark numbers. The HTC One will be available April 19 on Sprint and AT&T for $199 with contract ($299 for the 64 gig model on AT&T) and it will be available this spring from your favorite "uncarrier" T-Mobile. HTC is also selling an unlocked 32 gig model as well as the SIM unlocked and bootloader unlocked 64 gig developer edition for $575 and $650. For our review, we look at the AT&T 32 gig model.

The HTC One features a unibody aluminum casing that will be available in your choice of silver with white accents and black. It looks and feels like a high quality product with styling and design that rivals the iPhone 5. At 5 ounces it feels serious but not too heavy and the size is in line with other 4.5" to 5" smartphones. The phone has a micro SIM card slot but no microSD card slot and the micro USB port also supports USB OTG host (we've used it with flash drives) and MHL out for HDMI to a TV, monitor or projector.

Powered by a very fast Qualcomm Snapdragon 600 quad core 1.7GHz CPU with Adreno 320 graphics and 2 gigs of RAM, the One is currently the phone to beat for speed. The Samsung Galaxy S4 will soon be here with the same CPU, and will likely score similarly to the HTC One. But for now, the HTC One earns serious bragging rights with these benchmark scores:

Quadrant: 12,252AnTuTu: 24,589Geekbench 2: 2637Sunspider: 1155

Benchmarks only tell part of the story; in actual use the phone is very fast with none of that telltale Android lag and it multitasks like a champ. The phone also handles demanding 3D games like Real Racing 3 and Ravensword 2 beautifully. And yes, it does get a might toasty when playing those games for 15 minutes or more.

We had our doubts about HTC's new Ultrapixel camera that's just 4 megapixels, but just as with dedicated digital camera technology, a large sensor with bigger pixels really can make a revolutionary difference, particularly for low light photography and capturing fast motion scenes. The HTC takes better low light photos that we've ever seen with a camera phone, and it rarely needs the flash. Even daylight photos hold up well against the very good Nokia Lumia 920 and iPhone 5 with much higher megapixel ratings.
